I have sucessfully made backup copies of DVDs (-r) and have found that I cannot get them to play on Pioneer Model DV353. The same disk will play on various PC software players, my Toshiba SD-2800, Sony DVP-NS425P, and older Zenith with no problems. Does anyone know if this Pioneer Player will not read a DVDx Copy DVD-R for some reason? The player WILL play my own home videos created on the same PC using Studio 8, MyDVD, and a Memorex dual format burner with no problems. Very confusing why just this one player will not work.
